How the Huawei Watch 2 compares with smartwatches from Apple, Samsung, LG

Huawei on Sunday showed off its new Android Wear smartwatches at Mobile World Congress in Barcelona. The Huawei Watch 2 and Huawei Watch 2 Classic build on the success of the original model. Both watches are equipped with the new Snapdragon Wear 2100 chip and include an optical heart-rate sensor, GPS and NFC for mobile payments.

The main selling point, though, is the watch's battery life. The Huawei Watch 2 features a special low-power mode that can display the time and track steps for up to 25 days on a single charge.
